Progres AGRONIC 4000 Instruction Manual page 31

In order to postpone the irrigation some days, a
variation would , for example, irrigate in alternate days
but waiting initially 8 days: "Frequency02(08)", once 8
days have been taken away, the counter will take the
programmed ones.
Another irrigation modality would be pressing the
"MODE" key in order to work by daily activations. At
this modality the irrigation is carried out every day,
having the possibility to make several daily activations,
separated by a time to be determined by hours and
minutes. The first activation will take place at the pro-
grammed starting time.

P01-00 Frequency = 03(01)
P01-00 Activa.=05—01:30 Start = 15:10
The "Start" value corresponds to the time the
program will be activated. The timetable format is
from 00:00 to 23:59 hours. The time 00:00 is not valid.
Because of this reason the program will not work by
temporization.
There are some variations for the starting which
are the next:
•
The program can be started when another ends.
This programs enchainment is done by pro-
gramming at the starting time the value 99 (as the
enchainment code) and at the minutes the num-
ber of the program which precedes it. According
to this, as each program can deal with an irriga-
tion sequence of 12 sub-programs, when en-
chaining them will increase to 24, 36, 48, etc. If
the preceding program has various activations, it
will enchain at each one of them. Besides this the
first program moves the manual factor and the
determiners to the following programs.

• The program can be started by an element
(thermostat, level, etc.) connected to a digital in-
put with starting functions. To do so, it is neces-
sary to configure a determiner at program pa-
rameters [sector 6.7.]. The Agrónic 4000 allows to
work the 4,5 and 6 base determiners, thanks to
the fact of being already discharged. For the rest
of determiners it is necessary to activate the de-
terminers options.
•
Having the determiners function installed the irri-
gation can be started when a sensor value (soil-
moisture, temperature, etc.) reaches a determi-
nate level. It is necessary to configure a type 1 or
2 determiner at program parameters [sector
6.7.]. In order to program the reference value to
Start = 15:10
Start = 15:10
Start = 99:02
set on the starting, the "MODE" key has to be
pressed when the cursor is at the start value.
P03-00 SMTWTFS
•
Having the determiners option installed, an irriga-
tion by integration of a sensor (solar radiation
normally) in relation to the time lasted since the
previous irrigation can be started. It is necessary
to configure a type 3 determiner at program pa-
rameters [sector 6.7.]. In order to program the
reference value to set on the starting, the
"MODE" key has to be pressed when the cursor
is at the start value. At the program view [sector
12.2] the integration which is being accumulated
at each moment can be seen. Each time an irriga-
tion takes place, the total by integration goes to
0.

In the second line of the starting conditions
screen, the pre-irrigation and the post-irrigation
which will work is requested for each one of the sub-
programs.
The units that here have been programmed will
be discounted when irrigating in relation to the irriga-
tion units of each sub-program, in order to regulate
the application of the fertilizers to the irrigation water.
The fertilization will always start when the pre-
irrigation ends, finishing when the time or volume of
programmed fertilizer ends, but, avoiding always the
application of fertilizers during the post-irrigation units.
The following value is the irrigation manual fac-
tor (F=+00%), with which we can modify in more or
less, the irrigation values of all the sub-programs by
modifying only this value.
This value is calculated each time a sub-program
starts the irrigation. With the +00% value the same
units are maintained.
P01-00 SMTWTFS
Pre/Post = 010/030
Having the determiners option the fertigation can
be modified by the climatic factors, once configured at
program parameters [section 6.7].
In order to program the determiners factor, the
"MODE" key has to be pressed when the cursor is
placed at the "manual factor", and give a pulse for
each configured determiner. In order to give room to
the factor and to the determiner reference value, the
text "Pre/Post" disappears and these units are moved
to the left.
